Since the early 20th century, the ownership and usage of automobiles in the United States have rapidly increased, leading to large-scale highway construction. Almost simultaneously, in the context of commercial prosperity, outdoor billboards along highways continue to increase, becoming a serious problem affecting the landscape. However, this problem was not initially effectively regulated. In the 1960s, against the backdrop of the rise of environmentalism, President Johnson proposed the concept of "New Conservation" and actively promoted environmental legislation. In 1965, the Highway Beautification Act was enacted. However, after the Act's passage, the regulation of outdoor billboards faced many challenges such as insufficient funding, industry resistance, and unconstitutional accusations, ultimately failing to achieve any actual effect. In spite of this, the historical practices of regulating and governing outdoor billboards in the U.S., along with the new environmental ideas embodied in the 1965 Highway Beautification Act, remain noteworthy today. These ideas reflect Americans' pursuit of quality of life, while the Act's failure highlights the powerful influence of modern commercialism. [ABSTRACT FROM AUTHOR]

With the continuous advancement of large-scale high-grade highway construction and maintenance and repair projects, the demand for asphalt materials has been gradually increasing. As fossil materials are consumed, finding an alternative to petroleum asphalt materials has become an urgent need in the field of road engineering. This paper used corn stover tar as raw material and conducted resin treatment to prepare bio- bitumen. Based on the analysis of BOX-Behnken response surface, the resin yield was used as the evaluation index, the optimal process conditions for resin synthesis were as follows: phenolic molar ratio was 0.8, reaction time was 125 min, and straw tar addition was 10%. The results showed that with the increase of resinized products, the penetration degree of bio-bitumen also increased, which was higher than that of 70# petroleum asphalt. The ductility of B-PF bio-bitumen first increased and then decreased with the increasing of the content. However, the ductility of H-PF bio-bitumen decreased with the increasing of the dosage. Increasing the amount of bio-bitumen could reduce the softening point. The elongation and softening point of H-PF bio-bitumen were lower than 70# petroleum bitumen at 10% content, while the softening point and elongation of the bio-bitumen prepared at 20% content were lower than 70# petroleum bitumen.

In order to study the settlement of the existing subway tunnel below caused by road construction, on the basis of the construction road diagonally above the subway tunnel, a field tunnel settlement deformation measurement study was conducted to analyze the settlement curve of the subway tunnel in the roadbed grouting reinforcement, roadbed and pavement structure layer construction stages. A subway tunnel-soil-road model was established to simulate the slurry reinforcement process of road construction and the construction of roadbed and pavement structure layer, and the accuracy of the refined model was verified by comparing the calculated results of underpass tunnel settlement with the actual measured values on site. Based on this, the influence law of key parameters such as the total construction thickness of roadbed and pavement structure layer, the nature of road soil, the submerged soil layer of tunnel, and the strength of tunnel lining on the settlement of the subway tunnel was analyzed. The results show these as follows. the settlement value of the subway tunnel is positively correlated with the construction thickness. The presence of the road has less influence on the settlement of the tunnel, and its elastic modulus and Poisson's ratio have almost no influence on the settlement of the subway tunnel. The larger the elastic modulus of the lying soil layer, the less deformable the soil layer is, and the smaller the settlement of the subway tunnel is, the increase in the elastic modulus of the lining has less influence on the settlement of the subway tunnel instead.

At present, the national infrastructure construction market contains enormous opportunities and challenges, and the competition in the highway market is particularly evident. By elaborating the classification and construction process of highway construction, based on the overall situation of highway construction in the end of the 13th Five Year Plan and the highway policies in the 14th Five Year Plan in China, data analysis and comparison methods were adopted to analyze the market operation situation of major construction enterprises and the current main cooperation models in the market. Research results show that, the current domestic highway market is generally stable, and the construction of trunk roads has been saturated. There is a market demand for strengthening the highway chain network, which has led to the transformation of the domestic infrastructure industry towards green and intelligent directions. Based on the above analysis, operational suggestions were proposed from the aspects of supplementing and strengthening the shortcomings of operational elements, optimizing operational layout, and optimizing business models. First, the enterprise should rely on the advantages of the railway market, promoting the construction of a comprehensive transportation hub market that integrates railways, highways, water transportation, etc. Second, the enterprise should expand business development areas and extend the highway market based on new urbanization and rural revitalization. Technology innovation should be emphasized and used to empower the high-quality development of highway construction with the concept of "smart + green". [ABSTRACT FROM AUTHOR]

The existing highway construction monitoring systems are independently deployed. This paper proposes an intelligent monitoring system for highway construction based on remote wide area networks. By employing the tracking devices equipped with inertial measurement units and global positioning systems, the workers' activity space is monitored. People and equipment entering the site are registered by radio frequency identification tags with protective measures. Motion sensors are employed to monitor the changes in scaffolding, building structures, and highway low-grade inclinations. In addition, a light-weight object detection (LOD) algorithm is proposed to detect construction workers who fail to wear safety helmets. The LOD algorithm replaces the standard convolutional networks with depthwise separable convolution networks. It introduces the receptor field module, employs the LOD-NMS algorithm and Mish activation function, and sets an appropriate prior box according to the characteristics and ratios of people's heads in Asia, thus well balancing the precision and prediction efficiency. Experiments are conducted on the WIDER FACE open source data set and the real data sets. The results show LOD algorithm not only detects workers' safety helmets in real time with high precision, but also achieves higher recognition accuracy than traditional algorithms despite the low-resolution input images.

In order to explore the characteristics of carbon sink function restoration of ecosystems in the process of highway construction in grassland areas, taking the road ecosystem in Xilingol typical grassland area as the research object, the characteristics of carbon sink function among 4 typical disturbance modes (roller compaction, embankment, cutting and borrow site) of road ecosystem in typical grassland area under different vegetation restoration years (1, 5 and 15 a) were compared based on field measurements and space instead of time method. The results showed that, with the increase of restoration years, the vegetation community characteristics indicators increased significantly under different disturbance methods. Vegetation organic carbon content, soil organic carbon content and restoration period showed positive correlation, and showed restoration 15 a > restoration 5 a > restoration 1 a. The maximum value occurred when the restoration period was 15 a and the embankment vegetation carbon content was 143.65 gµkg-1 and the embankment soil carbon content was 14.33 gµkg-1. Under different restoration years, the order of organic carbon content in the four disturbed plots from high to low was embankment > cutting > fetch ground > rolling. The organic carbon content of the road embankment was higher than the other three samples at all three restoration years, and exceeded the native control by 21.6% at restoration 15 a. The results were of great significance for road ecosystem restoration and carbon sequestration function evaluation. [ABSTRACT FROM AUTHOR]

To explore the interaction and reasonable construction scheme of the close construction of roads and railways with a small clear distance, the influence of construction disturbance, construction sequence, timing of secondary lining construction and construction method on small clear distance tunnel is analyzed through numerical calculation with reference to the Yongzhou highway and railway tunnels of large intersection angle and small clear distance section, and small intersection angle and small clear distance section, and the construction scheme of small clear distance cross tunnel is determined. It is concluded that for the cross tunnel with large intersection angle and small clear distance, the plastic zone is transfixed and the initial support stress appears in the connection of the cross tunnel. The order of railway construction first followed by highway is chosen to reduce the plastic zone, the primary support force and the tension of the secondary lining, and to avoid the railway tunnel vault heave and the excessive highway tunnel arch waist convergence. The full section construction is selected to reduce the tension of the support, the bolt stress of the transverse channel and the pressure of the primary support of the railway tunnel and to avoid the stress deviation. For the cross tunnel with small intersection angle and small clear distance, the plastic zone is concentrated in the upper and lower sides of the tunnel and the intercalated rock in the cross tunnel, the horizontal deformation area of the cross tunnel is connected with a large initial deformation support in the vault of the highway tunnel. The first excavation of railway tunnel contributes to better plastic zone distribution of railway tunnel and to the optimal deformation and stress of surrounding rock and tunnel. The plastic zone around and under the arch of railway tunnel and the deformation and stress of rock and tunnel will be increased when secondary lining is applied after the excavation of highway tunnel. Therefore, the whole section construction is selected because it is optimal in bolt stress and tunnel deformation. [ABSTRACT FROM AUTHOR]

With the continuous growth of the number of motor vehicles in China, the existing urban road resources can no longer meet the traffic demand. Many cities are upgrading the existing roads, and frequent road construction has had a huge impact on urban traffic operation. Aiming at the characteristics of urban road structure, a traffic impact assessment method suitable for urban arterial work zones was proposed. Combined with the characteristics of intermittent flow facilities of urban roads, the concept of equivalent capacity was applied to give the traffic impact evaluation index of equivalent saturation urban arterial work zones. Based on the improved bureau of public road(BPR),model, a travel time calculation model suitable for urban roads was given, and an evaluation method of the reliability evaluation index of the travel time was provided. Taking into account the evaluation indicators of average delay, equivalent saturation, and evaluation index of the travel time reliability, a comprehensive evaluation method for the traffic impact of urban arterial work zones was proposed. The evaluation threshold for traffic impact in urban arterial work zones was given from three different dimensions: “point”“line”and “surface”. The process for determining the scope of traffic impact in urban arterial work zones was provided based on the threshold of traffic impact assessment. The simulation results show that the established traffic impact assessment method for construction area based on equivalent traffic capacity established solves the problem that the existing methods are difficult to calculate and difficult to apply in practice, and gives specific traffic impact assessment thresholds at different levels, overcoming the defect that traditional methods only determine the traffic impact assessment threshold from a single level.

In order to reveal the influence of highway construction on the natural grassland and ecological system in Qinghai-Tibet Plateau, two representative construction points at a distance of 17 km which are ongoing construction area of S10 Zhuoni-Hezuo expressway in Gannan Tibetan autonomous prefecture of Gansu province were investigated. The sampling sites were 10 and 500 m away from the construction red line, and the sampling dates were June and September 2021. Line transect method was used to collect the samples, and species composition, coverage, height and biomass of plant community were calculated; the composition of plant community and species diversity were analyzed by SPSS software, and the least significant difference(LSD)method was used to test the significance of the above indexes, meanwhile the influences of highway construction on plant species, growth and diversity were discussed. The results show that there are 86 plant species presenting in investigation sites and the important values of Kobresia capillifolia, K. tibetica and Elymus nutans are higher; there are no significant difference between two investigation sites or between two distances(10 and 500 m away from the red line of highway construction)in the same location for most of the indices; only Shannon index and biomass of plant have significant difference(P<0.05)in a few sampling sites, suggesting that there is little difference of plant community composition in the investigation sites and the different distances away from the red line of highway construction. The vegetation height, average height, biomass and Menhinick index of plant in September are significantly higher(P<0.05)than those in June, indicating that the plants away from the red line of highway construction recover naturally and grow normally through their own adaptation, although the highway construction partially destroys and affects the surrounding natural environment. In general, under strict control of construction behavior, plant communities and growth in different distances away from the red line of highway construction have little change, and the damages to the ecosystem are relatively small.

A new type of polyurethane emulsified asphalt（PUEA） tack coat with self-migration function was prepared by adding waterborne polyurethane to solve the problems of tracking in emulsified asphalt tack coat. Through the analysis of the trackless effect of PUEA tack coat with different content of waterborne polyurethane, the optimal content of waterborne polyurethane was 3%, and the PUEA-3（content of 3%） tack coat has excellent tracking resistance at 70 ℃.In addition, the analysis by FTIR, contact angle and electron microscope show that the polyurethane content on the upper surface of the PUEA tack coat was higher than that on the lower surface, and the polyurethane migrated to the surface of the tack coat during the forming process. The tracking resistance performance of tack coat was significantly improved at a small dosage of waterborne polyurethane. The PUEA tack coat with self-migration function has important application value in the construction and maintenance of highway asphalt pavement. [ABSTRACT FROM AUTHOR]

Objective In order to further promote the resource utilization of oil-based rock debris deoiling residue, the feasibility of preparing asphalt pavement from deoiling residue is studied by using deoiling residue, mineral powder and gravel as raw materials. Methods JTG/T F40-2004 Technical specification for construction of highway asphalt pavement, GB/T 30810-2014 Method for determination of leachable heavy metals in cement mortar and EA NEN 7375-2004 Standard for leaching characteristics of molded or integral block materials were used to investigate the product quality of asphalt surface test blocks prepared by replacing mineral powder with residual solid phase, and the effective releasable amount and releasing characteristics of heavy metals in asphalt surface were analyzed. Results The performance of the prepared asphalt pavement surface test block could meet the requirements of JTG/T F40 — 2004 when the content of residual solid phase is not higher than 4. 8% (mass fraction). The releasing rates of 11 heavy metals (arsenic, barium, cobalt, copper, chromium, manganese, molybdenum, nickel, lead, vanadium and zinc) in the leaching solution of asphalt surface test block were less than 1 %. The releasing mechanism of each heavy metal in the asphalt surface test block is different. The releasing mechanism of arsenic and chromium is mainly due to dissolution and the release mechanism of barium, cobalt, manganese, nickel and lead is mainly ascribed to surface scouring while the remaining heavy metals are controlled by diffusion. The releasing rate of each heavy metal was in the following order: barium

In order to further study the modification mechanism and fatigue characteristics of high modulus RCA modified asphalt, its performance is measured by three indexes, Brockfield viscosity, infrared spectrum, linear amplitude scanning and dielectric constant test. The basic indexes, fatigue properties, functional group changes of asphalt and the changes of asphalt components based on dielectric properties with different modifier contents are discussed, and grey correlation degree between the components and asphalt pavement performance index is analyzed. The results show that the optimum content of RCA modifier is 16.7% of asphalt mass. The modification of asphalt by RCA modifier is physical modification. Under low strain, the fatigue performance of RCA modified asphalt is better than that of base asphalt, and the strain dependence is higher. The fatigue life calculated by the new asphalt fatigue failure criterion has a good correlation with the fatigue life of asphalt mixture, and it is feasible to evaluate the fatigue resistance of RCA modified asphalt.
